Well....let's change that to something that is physically possible.

If you were travelling 99.99% the speed of light in one direction, and something else, say 1 light year away, was travelling in the opposite direction at 99.99% the speed of light. From YOUR perspective in the first ship, the light from the other ship would take....wait for it.....1 year.

Spacetime stretches and squishes based on your speed. That's WHY time dilation occurs.

Submission + - Mysterious substance found in human brain

Velcroman1 writes: "A mysterious molecule that turns people into modern-day Rip Van Winkles has been discovered in the brain, and it may be responsible for a rare disorder that has some sufferers sleeping more than 70 hours a week. The strange molecule, called a "somnogen," is believed to be at the root of the sleeping disorder, which in some cases also makes it difficult for people to wake up from their marathon sleep sessions. The somongen is made up of amino acids, just like a protein, and may keep sufferers bedridden for years, said David Rye, professor of neurology at Emory University School of Medicine and director of research for Emory Healthcare’s Sleep Center Clinic. “They feel as if they’re walking around in a fog – physically, but not mentally awake,” Rye said."

Only in direct line-of-sight, but technically...yes. One cell phone WILL cast a "shadow" for any directly behind it, just by the fact that this first phone's antenna is intercepting the signal. The cell tower is still putting out the same amount of signal power, however.

One small correction: The cell tower transmits the same signal power level, no matter where it goes or how it's used. So if a cell tower out in the Mojave desert puts out, say, 5 kilowatts and there's no cell phone around to receive its signal, then....the cell tower put out 5 kilowatt. Phones that recharge from the cell towers' transmission won't effect anyone else's phone reception.
